WILLIAM'B. EASTON, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE FRASER &

CHALMERS, OF SAME PLACE.

AMALGAMATlNG-PAN AN D SETTLER.

SPECIFICATION forming part of Letters Patent No. 593,767, dated November16, 1897. Application filed May 25,1897. Serial No. 638,154. (n6 model.)

To all whom it may concern.-

Be it known that I, WILLIAM B. EASTON, a citizen of the United States,residing at Ol1icago, in the county of Cook, State of Illinois, haveinvented certain new and useful Improvements in Amalgamating-Pans andSetand combination of parts described herein and defined in the claim.

Referring to the accompanying drawings, Figure 1 is an elevation, partlyin vertical section, of a settler-pan and enough of its operatingmechanism to illustrate the invention. Fig. 2 is a horizontal section ofa settler-pan on line 00 0c in Fig. l.

Like characters of reference refer to like parts throughout the drawingsand specification.

1 is the settler-pan, and l is the bottom thereof. Bolted or otherwiserigidly secured to the bottom 1 is the pan-cone 2, which passes upthrough the center of the pan. The cone 2 is hollow, and through itpasses the spindle 3, having the miter-gear 4 on its lower end in meshwith the bevel-gear 5 on the driven shaft. Surrounding the pan-cone 2 isthe driver 6, which may be raised or lowered by means of the hand-wheel7, attached to the driver-nut 6, which is threaded onto the spindle-stem3. The upper portion of the driver 6 is cylindrical in form, while thelower part is in the form of a spider, the four legs 6 of which areattached to the upper side of the muller-plate 8. The shoes 9 areattached to the under side of said muller-plate.

In the upper portion of the driver 6 is the annular channel 6, whichreceives the upper part of a piece of pipe 13, called an oilguard. Thelower edge of the oil-guard fits inside of the annular dish-shaped upperextremity 2 0f the pan-cone 2.

The interposition of the oil-guard in the annular chamber 6 between thespindle 3 and the driver 6 prevents the lubricant from being thrown bycentrifugal force from the spindle to the inner wall of the driver, and

from there passing down said inner wall into the pan. By placing theoil-guard as above described the centrifugal force throws the oil fromthe spindle to the inside of the oilguard, from whence it runs down intothe dish-shaped upper end of the pan-cone and follows down the spindle.The annular chan nel 6 is deep enough to admit raising the driver anydesired distance without freeing the upper end of the oil-guard.

The annular chamber 10 constitutes an oilcup into which oil finds itsway through the opening 11 from the channel 12, formed in the upper sideof the oil-cup. .From the oilchamber 10 the oil passes down around thespindle 3. In the sides of the spindle 3 are oil-grooves 3 which carryoil to the Whole circumference of the bearing in which the spindle turnsand also carry oil into the annular chamber 6 inside of the oil-guard.

What I claim as my invention, and desire to secure by Letters Patent,is-

In amalgamating-pans or settlers, the combination of a spindle, apan-cone provided with a dish-shaped top, a driver-head fixed at theupper end of the spindle and having an annular channel, and anoil-guard, the

upper end of the oil-guard being loosely inclosed in the annular channelin the driverhead, and having its lower end resting in the dish-shapedtop of the pan-cone, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.
